| Abstract: | Granitoid researches abroad became more prosperous in 1990s than in 1980s. This paper has made a review on the advances of the researches in five aspects: the evolution of the petrogenetic model for I_type and S_type granitoids from the restite model to the three component model; the new explanation on the geneses of magnetite series and ilmenite series granite, which are attributed to a difference in SO 2 content and SO 2/H 2S ratios in their source magmas rather than to their magnetite content (oxidized _ and reduced_type granites); the new synthetical classification of granitoids, with emphasis on the relationships between granitoid types, their origins and their geodynamic environments; the new ideas on collisional orogen granites, i.e., the introduction of the geneses of the peraluminons granitoids and the post_collisional strongly peraluminous granites; the development of the hypothesis on geodynamic environmentof the Archean TTG from the hot spot hypothesis to the hypothesis of the plate subduction. In the present paper, the authors try to expound the researchers' train of thought for raising and solving problems and ways of approaches in the course of their studies. It is evident that the researches in the granitoid field have entered a new stage of development. It has been developed from researches on individual intrusive bodies and suites to geodynamic researches on various granitoid types in a specific tectonic setting on a global scale. Well_typed and precisely_dated granitoids can help structural approaches and indicate the geodynamic environment. With some case studies, the use of granitoids as tracers of the geodynamic evolution is also proposed. |
